' ,Th aZLwh m it may concera Be it'knownthat I, 9. winn r, of Wilmington,

county of New Castle, State of Delaware, have invented anlmprovemeut 'in'iOar-Windows; and I do hereby declare the following to be a full, clear, and exact description of the same, I

My invention consists of a sash'for car-windows, (to' beused in connection with; the usual glazed and slatted sashes) upon which is stretched wire gauze of so fine a texture, that while itshall not interfere with the free circulation of air through tllewindow, nor exclude the light to any great extent, it will effectually prevent the admission into the can of particles of dust or of sparks from the locomotive, all of which is fully de- 1,.In order to enable othersislrilled in the art to make. and apply my invention, I will nowproceed to describe its construction and operation, 'reference being had to' the accompanying drawin'g,]which forms a part of this specification, and in which-,

. Figure-1 is a view of a portion of one side of a car showing a window with my improvement;

Figure"2,'- a section ofthe same, on the line l-2,

fig. 1;

1 Figurefi, a sectional plan view, on the line 3-4, fi 1 llig ure' 4, a view of a portion of fig. 3, drawn to an enlarged scale; and

'Eieure 5, a detached view of part of an ordinary carwindow.

Similar lettersrefer to similar parts throughout the several 1 views.

A represents a portion of one side of a passenger railwaybar, in, which is aw'indow, B, the latter being provided wi.,h the usual glazed and slatted sashes O and D, arranged to slide vertically in the frame, as best observed-in iig. 2. i

relative positions'oan be changed.

strip, there is an intrrvening unoccupied space, a, of a width nearly, if not quite as great as that occupied by either of the sashes.

This space I utilize by introducing into the same a third sash, 1 the division-strips y being first removed and replaced by metal strips, b, fig. 4, which are so bent as to serve as guides for the edges of the sash h, and at the same time to separate the several sashes sufiic'iently to permit them to be. operated freely and independently of each other.

The sash F is covered with wire gauze of so fine a texture, that when lowered to the bottom of the frame (the other sashes being raised) it will effectually prevent the admission of particles of dust, or of sparks from thelocomotive .intotheinterior. of the .icar, but will, at the same time, not interfere with the free circulation of air through the window, or exch'ide the light to anygreat extent. When not in use, the gauze sash can be raised into the window-frame, in, the same manner as the other sashes.

Although I prefer, especially in applying my invention to old cars, to arrange the several sashes in the manner above described, it will be evident that their For instance, the wire gauze sash might be arranged outside, for the purpose of protecting the glazed sash, which could then be placed in the centre.

Without, therefore, confining myself to'the exact arrangement of sashes above described,

-I claim, and desire to. secure by Letters Patent 1. The adjustable sash F, sliding in guides between the outer and inner sashes of a car-window, substantially as and for the purpose described.

2. The bent strips 7); arranged between the outer and inner sashes of a car-window, and guiding an intermediate sash, F, substantially as specified.

' In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
